If the number of currently processed tasks has reached the allowed limit, the backup infrastructure component will not start processing a new task until one of the currently running tasks finishes.ĭuring data protection or disaster recovery jobs, Veeam Backup & Replication creates a separate task per each disk of every VM added to the job. The Veeam Backup Service detects the number of tasks that required backup infrastructure components are currently processing, and analyzes the number of allowed tasks for these components. When a job starts, it informs the Veeam Backup Service about the list of tasks created for the job, and backup infrastructure resources that must be used for the job. The Veeam Backup Service is aware of all backup proxies and backup repositories in the backup infrastructure, and task limitation settings configured for them. Task limiting is performed by the Veeam Backup Service. In this case, Veeam Backup & Replication will create 6 tasks (1 task per each VM disk) and start processing 4 tasks in parallel. For example, you add a VM with 6 disks to a job and assign a VMware backup proxy that can process maximum 4 tasks concurrently for the job.
Task limits set for backup infrastructure components influence the job performance.
